The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
The atmosphereâs outer layer is called the corona (crown). In ultraviolet light, it is revealed to be full of loops of hot gas. These coronal loops may rise as high and as wide as 500,000 km (300,000 miles). The inner layer of the Sunâs atmosphere is a pinkish colour and is called the chromosphere (colour-sphere).rom Earth, observers cannot usually see the corona, or outer atmosphere of the Sun, because the photosphere (surface) is so bright. During a total eclipse, however, the moon blocks out the surface and we can see the Sunâs atmosphere.
